Spin round you can feel the breeze...

At such moments of extreme panic and anguish you do manage that trick with time: you are at last free from the illusion that it is linear. Because in panic, time stops: past, present and future exist as a single overwhelming force. You then, perversely, want time to appear to run forwards because the 'future' is the only place you can see an escape from this intolerable overload of feeling. But at such moments time doesn't move. And if time isn't running, then all events that we think of as past or future are actually happening simultaneously. That is the really terrifying thing. And you are subsumed. You're buried, as beneath an avalanche, by the weight of simultaneous events.
